I'm a bit new to the trading stuff, so please pardon If I screw up.
I've got 2 Coals I don't want, but I also want some energy to get some 5* Items in SK.
The solution?
Trade coal for energy!
...Kinda ironic considering coal is USED for energy anyway...
Anyway, I've had little success in-game, but I think It would bring more success If I posted the offer here.
If you think my Wants for it are too high or low, just tell me.
